During Christmas vacation, Phineas and Ferb's quest to show gratitude to Santa during Christmas may be doomed for failure, when Dr. Doofenshmirtz uses an invention that puts the entire town of Danville on Santa's naughty list.
Did You Know?
A Christmas themed version of the regular theme song was recorded, replacing the regular summer vacation activities with Christmas vacation activities. Due to this, Candace's line "Mom, Phineas and Ferb's making a title sequence!" has been changed to "Mom, Phineas and Ferb's making a Christmas special!". See more
When the boys ask Isabella if she is sad that Santa put Danville on the naughty list, she says that she celebrates Hanukkah. However, earlier when Phineas asked everyone if they wrote letters to Santa asking him for things, Isabella said that she did; and when he asked if they wrote Thank You notes for the presents they received from Santa, she said that she didn't. Why would she write letters to Santa and receive presents from him if she celebrates Hanukkah? See more
